IMPROVEMENT IN LUBRICATING AXLE-BOXES FOR VEHICLES.

Specification forming part of Letters Patent No. 133,895, dated December 10, 1872.

To all whom 'it may concern:

Beit known thatwe,' JAMEs SHAGKLETON and WILLIAM SHAGKLETON, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain /new and useful Improvements in Self-Oilin g Boxes for Carriage and' other Wheels, of which the following is av specication:

Our improvements relate to lubricating devices for carriage and other wheels; and the said improvements consist of an axle-box having at its inner end an annular drop-chamber formed in an external projection, and tapering channels formed in the longitudinallyprojecting ribs of the box, in combination with the oi1cup at the front end of the axle,

`with which said tapering rib-channels communicate, as will be more fully hereinafter described. In the accompanying drawing, Figure 1 represents an elevation of a hub-box embracing our improvements and a portion of a carriageaxle to which it is applied; Fig. 2 represents a longitudinal section thereof; Figy represents an interior view of the hub-box,

showin g its annular oil drop or chamber and Y the channels which connect it with the front oil-cup; and Fig. 4, a transverse section of the same at the line x :c of Fig. 2. i

The box A is provided'with an 4annular projection, B, pn its rear end, within which an annular drp-charnber, C,^for the oil is formed, so as tourbe outside of the inner diameter of the box A, as shown in Figs. 3 and 4.

This hollow annular projection B tits against the shoulder D on the axle E; and the oildrop C communicates, by two channels, c b, with the front end of the box. These channels a b are formed within the outside ribs F v of the box A, and taper gradually from the oil-drop chamber C to the end of thebox A, the object of which is to form a communication of the oil-supply cup Gr at the front with the oil-drop or receiving chamber C- at the rear of the box, the latter forming a reservoir for the waste oil, not only around the axlebearing H, but for the shoulder D of the axle E, against which the enlarged `end B of the box revolves, so that the waste or drop chamber C holds the oil from the box and gives it out over the axle-shoulder.

An additional advantage of the dropfehamber is that its projecting case B forms a shoul der outside of the box, against which the hub.

is secured.

The end of the axle-bearing H is provided with a screwstem,I, to receive the screw-nut J, which holds the wheel upon the axle. The

outer -ed of the box is provided with a screwthread, c, for two purpo'sesiirst, to receive a screw-collar, K, which is screwed firmly against the end of the hub; and, second, to

receive the screw oil-cup Of, which` is screwed Y rmly against the separate collar K, a leather or rubber washer, e, being placed between them to make the joint tight. The separate collar K has notches V f by which to screw it against the hub, and it is thus arranged separately from the' oil-cup Gr to relieve the latter of strain and to receive the strain from the hub, which would otherwise be upon the vwedges which secure the hub to the box.

This separate collar K, screwing directly upon the projecting end of the box, gives the advantage of being` tightened from time to time so as to keep the hub always tight, while the boxribs F prevent it from -turning there on. The oil-cup G screws over the holdingnut J, and, in connection with the waste or drop chamber C, will hold oil enough to last from one to two months, according to the size and character of the vehicle. The holding `nut J for the wheel should be clamped against the end of the axle-bearing H, soas to leave the box-channels a b always in communication with the.cupchamber. The oil-cup'G is supplied, without removing it from the box,

through an opening therein closed by a screw.`

Having described our improvements, we claim The axle-box A, having the annular dropchamber C and the tapering channels a b Y formed, respectively, in the collar B and the ribs F, in combination with the oil-cup G and the axle H, as described.

In testimony whereof we have hereunto set our hands this 16th day of September, A. D.

JAMES SHACKLETON. WILLIAM SHAOKLETON.
